Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. In the opinion of management, all necessary adjustments (which consists of only normal recurring items) have been made to fairly present the Condensed Consolidated Financial Statements for the interim periods presented. Results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (“SEC”). Fair Value Measurements The Company categorizes its fair value measurements according to a three-level hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are defined as follows: • Level 1 – Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date; • Level 2 – Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active; and • Level 3 – Inputs that are unobservable and require significant management judgment or estimation. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. The carrying amounts of cash and cash equivalents and fees receivable approximate fair value due to the immediate or short-term maturity of these financial instruments. Investments Investments primarily consist of investments in GCM Funds and other funds the Company does not control, but is deemed to exert significant influence, and are generally accounted for using the equity method of accounting. Under the equity method of accounting, the Company records its share of the underlying income or loss of such entities, which reflects the net asset value of such investments. Management believes the net asset value of the funds is representative of fair value. The resulting gains and losses are included as investment income in the Condensed Consolidated Statements of Income (Loss). The Company’s equity method investments in the GCM Funds investing in private equity, real estate and infrastructure (“GCM PEREI Funds”) are valued based on the most recent available information, which typically has a delay of up to three months due to the timing of financial information received from the investments held by the GCM PEREI Funds. The Company records its share of capital contributions to and distributions from the GCM PEREI Funds within investments in the Condensed Consolidated Statements of Financial Condition during the three-month lag period. To the extent that management is aware of material events that affect the GCM PEREI Funds during the intervening period, the impact of the events would be disclosed in the notes to the Condensed Consolidated Financial Statements. Certain subsidiaries which hold the general partner capital interest in the GCM Funds are not wholly owned, and as such, the portion of the Company’s investments owned by limited partners in those subsidiaries are reflected within noncontrolling interests in the Condensed Consolidated Statements of Financial Condition. For certain other debt investments, the Company has elected the fair value option. Such election is irrevocable and is made at the investment level at initial recognition. The debt investments are not publicly traded and are a Level 3 fair value measurement. For investments carried at fair value, the Company records the increase or decrease in fair value as investment income in the Condensed Consolidated Statements of Income (Loss). See Note 5 for additional information regarding the Company’s other investments. Rece ntly Issued Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures . ASU 2023-07 scopes in entities with a single reportable segment and requires those entities to provide all disclosures required in Topic 280, requires that current annual disclosures about a reportable segment’s profit or loss and assets also be provided in interim periods and requires other various new disclosures. Enhanced reporting requirements for all entities includes disclosure of (1) significant segment expenses, (2) the title and position of the chief operating decision maker (the “CODM”) and (3) how the CODM uses disclosed measure(s) of a segment’s profit or loss in assessing segment performance and allocating resources. This guidance is effective for public entities for fiscal years beginning after December 15, 2023 and for interim periods within fiscal years beginning after December 15, 2024. Companies are required to apply the amendments retrospectively to all prior periods presented in the financial statements and early adoption is permitted. The Company is evaluating this guidance and currently expects that adoption will result in new disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . ASU 2023-09 requires enhanced income tax disclosures including disclosures of specific categories in the rate reconciliation and additional information for reconciling items that meet a quantitative threshold, additional disclosures about income taxes paid, and disclosure of pre-tax income or loss from continuing operations disaggregated between domestic and foreign income or loss. This guidance is effective for public business entities for fiscal years beginning after December 15, 2024. Companies should provide the enhanced disclosures on a prospective basis, however retrospective application is permitted. Early adoption is permitted for annual financial statements that have not yet been issued.

Fair Value Measurements	Fair Value Measurements The following table summarizes the Company’s assets and liabilities measured at fair value on a recurring basis and level of inputs used for such measurements as of September 30, 2024 and December 31, 2023: Fair Value as of September 30, 2024 Level 1 Level 2 Level 3 Total Assets Money market funds $ 47,110 $ — $ — $ 47,110 Other investments — — 11,665 11,665 Total assets $ 47,110 $ — $ 11,665 $ 58,775 Liabilities Public warrants $ 14,771 $ — $ — $ 14,771 Private warrants — — 950 950 Interest rate derivatives — 15,680 — 15,680 Total liabilities $ 14,771 $ 15,680 $ 950 $ 31,401 Fair Value as of December 31, 2023 Level 1 Level 2 Level 3 Total Assets Money market funds $ 10,282 $ — $ — $ 10,282 Other investments — — 11,192 11,192 Total assets $ 10,282 $ — $ 11,192 $ 21,474 Liabilities Public warrants $ 6,042 $ — $ — $ 6,042 Private warrants — — 389 389 Interest rate derivatives — 7,469 — 7,469 Total liabilities $ 6,042 $ 7,469 $ 389 $ 13,900 Money Market Funds Money market funds are valued using quoted market prices and are included in cash and cash equivalents in the Condensed Consolidated Statements of Financial Condition. Interest Rate Derivatives Management determines the fair value of its interest rate derivative agreements based on the present value of expected future cash flows based on observable future rates applicable to each swap contract using linear interpolation, inclusive of the risk of non-performance, using a discount rate appropriate for the duration. See Note 12 for additional information regarding interest rate derivatives. Other Investments Investments in the subordinated notes of a structured alternatives investment solution are not publicly traded and are classified as Level 3. Management determines the fair value of these other investments using a discounted cash flow analysis (“Cash Flow Analysis”), which includes assumptions regarding the expected deployment and realization timing of private investments. The position was classified as Level 3 as of September 30, 2024 and December 31, 2023 because of the use of significant unobservable inputs in the Cash Flow Analysis as follows: As of September 30, 2024 As of December 31, 2023 Impact to Valuation from an Increase in Input (2) Significant Unobservable Inputs (1) Range Weighted Average Range Weighted Average Discount rate (3) 25.8% – 27.8% 26.8 % 26.5% - 27.5% 27.0 % Decrease Expected remaining term (years) 8 – 12 N/A 8 – 12 N/A Decrease Expected return – liquid assets (4) 4.0% – 5.0% 4.1 % 2.0% - 5.0% 4.3 % Increase Expected total value to paid in capital – private assets (5) 1.55x – 2.12x 1.86x 1.55x – 2.05x 1.87x Increase ____________ (1) In determining these inputs, management considers the following factors including, but not limited to: liquidity, estimated yield, capital deployment, diversified multi-strategy appreciation, expected net multiple of investment capital across private assets investments, annual operating expenses, as well as investment guidelines such as concentration limits, position size, and investment periods. (2) Unless otherwise noted, this column represents the directional change in fair value of the Level 3 investments that would result from an increase to the corresponding unobservable input. A decrease to the unobservable input would have the opposite effect. (3) The discount rate was based on the relevant benchmark rate, spread, and yield migrations on related securitized assets. (4) Inputs were weighted based on actual and estimated expected return included in the range. (5) Inputs were weighted based on the actual and estimated commitments to the respective private asset investments included in the range . The resulting fair values of $11.7 million and $11.2 million were recorded within investments in the Condensed Consolidated Statements of Financial Condition as of September 30, 2024 and December 31, 2023, respectively. The following table presents changes in Level 3 assets measured at fair value for the three and nine months ended September 30, 2024 and 2023: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Balance at beginning of period $ 11,779 $ 10,690 $ 11,192 $ 10,007 Change in fair value (114) 367 473 1,050 Balance at end of period $ 11,665 $ 11,057 $ 11,665 $ 11,057 Public Warrants The public warrants are valued using quoted market prices on the Nasdaq Stock Market LLC under the ticker GCMGW. Private Warrants The private warrants were classified as Level 3 as of September 30, 2024 and December 31, 2023 because of the use of significant unobservable inputs in the valuation, however the overall private warrant valuation and change in fair value are not material to the Condensed Consolidated Financial Statements. The valuations for the private warrants were determined to be $1.06 and $0.43 per unit as of September 30, 2024 and December 31, 2023, respectively. The resulting fair values of $1.0 million and $0.4 million were recorded within warrant liabilities in the Condensed Consolidated Statements of Financial Condition as of September 30, 2024 and December 31, 2023, respectively. See Note 7 for additional information regarding the warrant activity. The following table presents changes in Level 3 liabilities measured at fair value for the three and nine months ended September 30, 2024 and 2023: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Balance at beginning of period $ 529 $ 314 $ 389 $ 475 Change in fair value 421 21 561 (140) Balance at end of period $ 950 $ 335 $ 950 $ 335

The delivery of vested RSUs will be reduced by the number of shares withheld to satisfy statutory withholding tax obligations as well as RSUs that are settled in cash. Dividends Dividends are reflected in the Condensed Consolidated Statements of Equity (Deficit) when declared by the Board of Directors. The table below summarizes dividends declared to date during 2024: Declaration Date Record Date Payment Date Dividend per Common Share February 8, 2024 March 1, 2024 March 15, 2024 $0.11 May 6, 2024 June 3, 2024 June 17, 2024 $0.11 August 7, 2024 September 3, 2024 September 17, 2024 $0.11 November 7, 2024 December 2, 2024 December 16, 2024 $0.11 Dividend equivalent payments of $1.8 million were accrued for holders of RSUs as of September 30, 2024. Distributions to partners represent distributions made to GCMH Equityholders. Stock Repurchase Plan On August 6, 2021, GCMG’s Board of Directors authorized a stock repurchase plan which may be used to repurchase shares of the Company’s outstanding Class A common stock and warrants to purchase shares of Class A common stock. Class A common stock and warrants may be repurchased from time to time in open market transactions, in privately negotiated transactions, including with employees or otherwise, pursuant to the requirements of Rule 10b5-1 and Rule 10b-18 of the Exchange Act, as well as to retire (by cash settlement or the payment of tax withholding amounts upon net settlement) equity-based awards granted under our 2020 Incentive Award Plan, as amended and restated (and any successor plan thereto), with the terms and conditions of these repurchases depending on legal requirements, price, market and economic conditions and other factors. The Company is not obligated under the terms of the plan to repurchase any of its Class A common stock or warrants, the program has no expiration date and the Company may suspend or terminate the program at any time without prior notice. Any shares of Class A common stock and any warrants repurchased as part of this program will be canceled. GCMG’s Board of Directors has made subsequent increases to its original stock repurchase authorization amount for shares and warrants. As of December 31, 2023, the total authorization was $115 million, excluding fees and expenses. On February 8, 2024, GCMG’s Board of Directors increased the firm's existing repurchase authorization by $25 million , from $115 million to $140 million.

Warrants	Warrants The public and private warrants meet the definition of a derivative under ASC 815 and the Company records these warrants as liabilities in the Condensed Consolidated Statements of Financial Condition at fair value, with subsequent changes in their respective fair values recorded in the change in fair value of warrant liabilities within the Condensed Consolidated Statements of Income (Loss) at each reporting date. Each public warrant entitles the registered holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment. The warrants expire 5 years after the consummation of the Transaction, or earlier upon redemption or liquidation. The public warrant holders do not have the rights or privileges of holders of Class A common stock and any voting rights until they exercise their warrants and receive shares of Class A common stock. After the issuance of shares of Class A common stock, upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders. The private placement warrants (including the Class A common stock issuable upon exercise of the private placement warrants) will not be redeemable by the Company so long as they are held by CF Sponsor, Holdings or their permitted transferees. CF Sponsor, Holdings or their permitted transferees, have the option to exercise the private placement warrants on a cashless basis. No warrants were exercised or repurchased during the three and nine months ended September 30, 2024 and 2023. The Company had 16,784,970 of public warrants and 900,000 of private warrants outstanding as of each of September 30, 2024 and December 31, 2023.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities The Company consolidates certain VIEs when it is determined that the Company is the primary beneficiary. The Company holds variable interests in certain entities that are VIEs which are not consolidated, as it is determined that the Company is not the primary beneficiary. The Company’s involvement with such entities is generally in the form of direct equity interests in, and fee arrangements with, the entities in which it also serves as the general partner or managing member. The Company evaluated its variable interests in the VIEs and determined it is not considered the primary beneficiary of the entities primarily because it does not have interests in the entities that could potentially be significant. No reconsideration events that caused a change in the Company’s consolidation conclusions occurred during either the nine months ended September 30, 2024 or the year ended December 31, 2023. As of September 30, 2024 and December 31, 2023, the total unfunded commitments from the special limited partner and general partners to the unconsolidated VIEs were $47.7 million and $42.1 million, respectively. These commitments are the primary source of financing for the unconsolidated VIEs. The following table sets forth certain information regarding the VIEs in which the Company holds a variable interest but does not consolidate. The assets recognized on the Company’s Condensed Consolidated Statements of Financial Condition relate to the Company’s interests in and management fees, incentive fees and third party costs receivables from these non-consolidated VIEs. The Company’s maximum exposure to loss relating to non-consolidated VIEs as of September 30, 2024 and December 31, 2023 were as follows: As of September 30, 2024 December 31, 2023 Investments $ 119,855 $ 102,109 Receivables 18,044 16,324 Maximum exposure to loss $ 137,899 $ 118,433 The above table includes investments in VIEs which are owned by noncontrolling interest holders of approximately $36.3 million and $30.9 million as of September 30, 2024 and December 31, 2023, respectively.

Employee Compensation and Benefits	Employee Compensation and Benefits For the three and nine months ended September 30, 2024 and 2023, employee compensation and benefits consisted of the following: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Cash-based employee compensation and benefits $ 37,318 $ 39,148 $ 113,324 $ 122,292 Equity-based compensation 3,908 3,437 34,713 33,045 Partnership interest-based compensation 13,435 14,958 55,025 89,182 Carried interest compensation 12,038 13,777 21,440 24,894 Cash-based incentive fee related compensation 6,528 4,712 15,977 7,177 Other non-cash compensation 90 381 440 915 Total employee compensation and benefits $ 73,317 $ 76,413 $ 240,919 $ 277,505 Partnership Interest in Holdings, Holdings II and Management LLC Payments and settlements for partnership interest awards to the employees are made by GCMH Equityholders. As a result, the Company records a non-cash profits interest compensation charge and an offsetting deemed contribution to equity (deficit) to reflect the payments or settlements made or owed by the GCMH Equityholders. Since payments or settlements are made by Holdings, Holdings II and Management LLC, the expense that is pushed down to GCMH and the offsetting deemed contribution are each attributed solely to noncontrolling interests in GCMH. Any liability related to the awards is recognized at Holdings, Holdings II or Management LLC as Holdings, Holdings II or Management LLC is the party responsible for satisfying the obligation, and is not shown in the Company’s Condensed Consolidated Financial Statements. The Company has recorded deemed contributions to equity (deficit) from Holdings, Holdings II and Management LLC of $13.4 million and $15.0 million for the three months ended September 30, 2024 and 2023, respectively, and $55.0 million and $89.2 million for the nine months ended September 30, 2024 and 2023, respectively, for partnership interest-based compensation expense which was or will ultimately be paid or settled by Holdings, Holdings II or Management LLC. GCMH Equityholders have modified awards to certain individuals upon their voluntary retirement or intention to retire as employees. These awards generally include a stated target amount that, upon payment, terminates the recipient’s rights to future distributions and allows for a lump sum buy-out of the awards, at the discretion of the managing member of Holdings, Holdings II, and Management LLC. The awards are accounted for as partnership interest-based compensation at the present value of these expected future payments, in the period the employees accepted the offer. The Company recognized $18.5 million in partnership interest-based compensation expense related to award modifications for the nine months ended September 30, 2024, and none was recognized for the three months ended September 30, 2024 and each of the three and nine months ended September 30, 2023 (other than as discussed for the Holdings Awards below) . The liability associated with awards that contain a stated target has been retained by Holdings as of September 30, 2024 and December 31, 2023 and is re-measured at each reporting date, with any corresponding changes in liability being reflected as employee compensation and benefits expense of the Company. No recipients had unvested stated target payments as of September 30, 2024 and 2023 . The Company recognized partnership interest-based compensation expense of $4.2 million and $3.7 million for the three months ended September 30, 2024 and 2023, respectively, and $9.0 million and $17.9 million for the nine months September 30, 2024 and 2023, respectively, related to profits interest awards that are in substance profit-sharing arrangements. GCMH Equityholders Awards In the year ended December 31, 2022, GCMH Equityholders entered into agreements that will transfer equity ownership between certain existing employee members of the GCMH Equityholders (“GCMH Equityholders Awards”). The GCMH Equityholders Awards will entitle recipients to receive Class A common stock upon vesting. The non-cash awards serve to transfer equity ownership from existing GCMH Equityholders to other existing member employees upon vesting. The GCMH Equityholders Awards do not dilute Class A common stockholders and do not impact cash flows of the Company. The GCMH Equityholders Awards are accounted for under ASC 718, Compensation—Stock Compensation . The awards generally will vest in May 2025 and do not entitle the recipients to dividends or distributions made on Class A common stock during the vesting period. As such, the fair value of the GCMH Equityholders Awards is based on the closing price of Class A common stock on the accounting grant date less the present value of dividends expected to be paid during the vesting period. GCMH Equityholders can settle the awards at various dates after vesting by exchanging outstanding GCMH common units or by otherwise acquiring and delivering Class A common stock, and therefore the vesting of such awards will not dilute Class A common stockholders. As such, the expense that is pushed down to GCMH and the offsetting deemed contribution are each attributed solely to noncontrolling interests in GCMH, consistent with the accounting for payments to employees described above. The GCMH Equityholders Awards of 7,169,415 units had an aggregate grant date fair value of $53.4 million, or an average grant date fair value of $7.45 per unit. The Company recognized partnership interest-based compensation expense related to the GCMH Equityholders Awards of $5.5 million for each of the three months ended September 30, 2024 and 2023, and $16.4 million for each of the nine mont hs ended September 30, 2024 and 2023. As of September 30, 2024 , total unrecognized compensation expense related to unvested GCMH Equityholders Awards was $12.7 million and is expected to be recognized over the remaining weighted average period of 0.6 years. Holdings Awards On May 9, 2023, Holdings entered into amended and restated participation certificates with existing employee members (“Holdings Awards”). The Holdings Awards entitle recipients to a stated percentage, or minimum allocable share, of distributions from Holdings, as well as a profits interest with respect to net sale proceeds from dispositions of Holdings properties after certain threshold distributions to other members. Pursuant to ASC 505, the Holdings Awards will be recognized as compensation expense with a corresponding deemed contribution and are accounted for under ASC 718, Compensation—Stock Compensation as the awards have characteristics that are more akin to the risks and rewards of equity ownership in Holdings. These awards do not dilute Class A common stockholders or impact net cash flows of the Company. Certain of these existing employee members were previously awarded target amounts that entitled them to a stated percentage, or minimum allocable share, of distributions from Holdings until they received a sum certain. Those target amounts represented by those sums, which were previously recorded as partnership interest-based compensation, were reduced to zero in the amended and restated participation certificates. As a result, target amounts that were previously recorded as partnership interest-based compensation were reversed, while partnership interest-based compensation associated with the amended and restated participation certificates is recorded. The Holdings Awards had an aggregate grant date fair value of $155.5 million, which was partially offset when recognized in expense by $80.0 million target amounts reversed during the year ended December 31, 2023. The fair value of the Holdings Awards was determined by a third-party valuation firm utilizing a discounted cash flow analysis for the minimum allocable share and a Monte Carlo simulation valuation model for the profits interest with respect to net sale proceeds from dispositions of Holdings properties after the threshold distributions. Significant valuation inputs and assumptions included Holdings projected financial information and distributions, an estimated 10 year holding period, a 15.4% cost of equity, a 13.0% weighted average cost of capital, a 35% volatility assumption, the likelihood of a defined conversion event, a 40% discount for lack of marketability, and the fair value of reference properties that determine the threshold distributions for the profits interest with respect to net sale proceeds. The resulting fair value of the Holdings Awards is pushed down from Holdings to the Company and recorded as compensation expense. A portion of the Holdings Awards were vested upon grant, resulting in immediate expense recognition. The Company recognized partnership interest-based compensation expense related to the Holdings Awards of $3.7 million and $11.1 million for the three and nine months ended September 30, 2024, respectively, and $5.8 million and $54.9 million for the three and nine months ended September 30, 2023, respectively. A portion of the Holdings Awards will vest and are being expensed over a requisite service period through December 31, 2024. As of September 30, 2024 , total unrecognized compensation expense related to unvested Holdings Awards was $3.7 million and is expected to be recognized over the remaining weighted average period of 0.3 years. Other Other consists of employee compensation and benefits expense related to deferred compensation programs and other awards that represent investments made in GCM Funds on behalf of the employees.

In 2021, the Company amended its Senior Loan to extend the maturity date to February 24, 2028 and increased the aggregate principal amount thereunder to $400.0 million (“2028 Term Loans”) . Through June 30, 2023, the 2028 Term Loans had an interest rate margin of 2.50% over the LIBOR, subject to a 0.50% LIBOR floor. On June 29, 2023, the Company entered into Amendment No. 7 to the Credit Agreement to incorporate changes for the contemplated transition to the Term Secured Overnight Financing Rate (“Term SOFR”), and on July 1, 2023, in conjunction with a Benchmark Transition Event, the interest rate defaulted to the Term SOFR plus a Benchmark Replacement Adjustment of 0.11% as recommended by the Relevant Governmental Body (all terms as defined in the Amended Credit Agreement). On May 21, 2024, the Company entered into Amendment No. 8 to the Credit Agreement to, among other things, increase and extend the 2028 Term Loans. The amendment increased the aggregate principal amount from $388.0 million to $438.0 million, extended the maturity date from February 24, 2028 to February 25, 2030 (as increased and extended, the “2030 Term Loans”), decreased the interest rate margin to 2.25% over Term SOFR, and removed the Benchmark Replacement Adjustment of 0.11%. As a result of the amendment and extension, the Company capitalized $0.4 million of debt issuances costs related to payments to lenders, which is recorded within debt in the Condensed Consolidated Statements of Financial Condition, and expensed $3.0 million of third-party costs which is recorded within general, administrative and other in the Condensed Consolidated Statements of Income (Loss) for the nine months ended September 30, 2024. In addition, the Company recorded an expense of $0.2 million related to the partial extinguishment of certain lenders, which is recorded within other income (expense) in the Condensed Consolidated Statements of Income (Loss) for the nine months ended September 30, 2024. From June 30, 2021 until May 21, 2024 quarterly principal payments of $1.0 million were required to be made toward the 2028 Term Loans (less any reduction for prior or future voluntary or mandatory prepayments of principal). As part of Amendment No. 8 to the Credit Agreement, quarterly principal payments of $1.1 million are required to be made toward the 2030 Term Loans beginning July 1, 2024 (less any reduction for prior or future voluntary or mandatory prepayments of principal). In addition to the scheduled principal repayments, the Company is required to offer to make prepayments of Consolidated Excess Cash Flow (“Cash Flow Payments”) no later than five days following the date the quarterly financial statements are due if the leverage ratio exceeds certain thresholds in the Amended Credit Agreement. The Cash Flow Payments were calculated as defined in the Senior Loan agreement based on a percentage of calculated excess cash. During the three and nine months ended September 30, 2024, the Company was not required to offer to make any Cash Flow Payments. As of September 30, 2024 and December 31, 2023, $436.9 million and $389.0 million of 2028 Term Loans were outstanding, respectively, with weighted average interest rates of 7.75% and 7.59% for the nine months ended September 30, 2024 and year ended December 31, 2023 , respectively. Under the credit and guaranty agreement governing the terms of the Senior Loan, the Company must maintain certain leverage and interest coverage ratios. The credit and guaranty agreement also contains other covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur debt and restrict the Company and its subsidiaries ability to merge or consolidate, or sell or convey all or substantially all of the Company’s assets. As of September 30, 2024, the Company was in compliance with all covenants. GCMH Equityholders and IntermediateCo have executed a pledge agreement (“Pledge Agreement”) and security agreement (“Security Agreement”) with the lenders of the Senior Loan. Under the Pledge Agreement, GCMH Equityholders and IntermediateCo have agreed to secure the obligations under the Senior Loan by pledging its interests in GCMH as collateral against the repayment of the Senior Loan, and GCMH has agreed to secure the obligations under the Senior Loan by granting a security interest in and continuing lien on the collateral described in the Security Agreement. The Pledge Agreement and Security Agreement will remain in effect until such time as all obligations relating to the Senior Loan have been fulfilled. Credit Facility Concurrent with the issuance of the Senior Loan, the Company entered into a $50.0 million revolving credit facility (“Credit Facility”). The Credit Facility maturity date was extended from February 24, 2026 to February 24, 2028 as part of the Amended Credit Agreement No. 8, and carries an unused commitment fee of up to 0.50% per annum. There were no outstanding borrowings related to the Credit Facility as of each of September 30, 2024 and December 31, 2023. Other Certain subsidiaries of the Company agree to jointly and severally guarantee, as primary obligors and not merely as surety guarantees the obligations of their parent entity, GCMH. Amortization of deferred debt issuance costs was $0.2 million and $0.3 million for the three months ended September 30, 2024 and 2023, and $0.7 million and $0.8 million for the nine months ended September 30, 2024 and 2023. These amounts were recorded within interest expense in the Condensed Consolidated Statements of Income (Loss). The carrying value of the Senior Loan, excluding the unamortized debt issuance costs presented as a reduction to the principal balance, approximated the fair value as of September 30, 2024 and December 31, 2023 . As the Senior Loan was not accounted for at fair value, it was not included in the Company’s fair value hierarchy in Note 5, however had it been included, it would have been classified in Level 2.

(2) Refer to Note 11 regarding the interest rate on the 2028 Term Loans for the July 1, 2023 Benchmark Transition Event. The floating rate received under the interest rate swap also defaulted to Term SOFR plus a Benchmark Replacement Adjustment concurrent with the Benchmark Transition Event. (3) Represents the date at which the derivative is in effect and the Company is contractually required to begin payment of interest under the terms of the agreement. A rollforward of the amounts in accumulated other comprehensive income (loss) (“AOCI”) related to interest rate derivatives designated as cash flow hedges is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Derivative gain at beginning of period $ 22,422 $ 29,641 $ 21,806 $ 29,130 Amount recognized in other comprehensive income (loss) (1) (10,915) 5,690 (4,873) 9,678 Amount reclassified from accumulated other comprehensive income (loss) to interest expense (2,798) (2,661) (8,224) (6,138) Derivative gain at end of period 8,709 32,670 8,709 32,670 Less: gain attributable to noncontrolling interests in GCMH 7,690 26,885 7,690 26,885 Derivative gain at end of period, net $ 1,019 $ 5,785 $ 1,019 $ 5,785 ____________ (1) Net tax benefit of $0.9 million and $0.8 million for the three and nine months ended September 30, 2024, respectively, and an immaterial tax impact for each of the three and nine months ended September 30, 2023. In February 2021, the Company terminated derivative instruments which were entered into in 2017. In October 2022, the Company terminated derivative instruments which were entered into in 2021 and received $40.3 million of cash for the fair market value of the interest rate swaps at termination. The amounts previously recorded as hedges in AOCI will remain in AOCI and will be recorded in interest expense within the Condensed Consolidated Statements of Comprehensive Income (Loss) over the original lives of the derivative instruments. The Company reclassified $1.9 million for each of the three months ended September 30, 2024 and 2023, and $5.7 million and $4.8 million for the nine months ended September 30, 2024 and 2023, respectively, from AOCI to interest expense relating to the derivative instruments terminated that initially qualified for hedge accounting. The net impact of these reclassifications decreased interest expense for each of the three and nine months ended September 30, 2024 and 2023, respectively. Effective on November 1, 2022 , the Company entered into a swap agreement to hedge interest rate risk related to payments made for the 2028 Term Loans that has a notional amount of $300 million and a fixed rate of 4.37%. The swap agreement and the 2028 Term Loans had a 0.50% LIBOR floor through June 30, 2023 and defaulted to Term SOFR plus a Benchmark Replacement Adjustment on July 1, 2023 at the Benchmark Transition Event as discussed in Note 11. The swap was determined to be an effective cash flow hedge at inception based on a comparison of critical terms and remained an effective cash flow hedge at and following the Benchmark Transition Event. Effective on May 31, 2024, the Company entered into a swap agreement to hedge interest rate risk related to payments made for the increase in aggregate principal amount of the 2030 Term Loans that has a notional amount of $28.5 million and a fixed rate of 4.47%. The swap agreement and 2030 Term Loans have a 0.50% Term SOFR floor. The swap was determined to be an effective cash flow hedge at inception based on a comparison of critical terms. On May 23, 2024, the Company entered into a forward-starting swap agreement to hedge interest rate risk related to payments made during the extended maturity of the 2030 Term Loans that has an effective date of February 2028, a notional amount of $317.0 million, and a fixed rate of 4.17%. The forward-starting swap agreement and 2030 Term Loans have a 0.50% Term SOFR floor. The swap was determined to be an effective cash flow hedge at inception based on a comparison of critical terms. The fair values of the interest rate swaps are based on observable market inputs and represent the net amount required to terminate the positions, taking into consideration market rates and non-performance risk.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases The Company has entered into operating lease agreements for office space. The Company leases office space in various countries around the world and maintains its headquarters in Chicago, Illinois, where it leases primary office space . The leases contain rent escalation clauses based on increases in base rent, real estate taxes and operating expenses. When determining the lease term, the Company generally does not include options to renew as it is not reasonably certain at contract inception that the Company will exercise the option(s). As the implicit rate is not generally readily determinable, the Company uses its incremental borrowing rate to determine the present value of future minimum lease payments. In January 2024, the Company executed an agreement to lease office space for its United Kingdom office. The new space will replace the Company’s existing United Kingdom office space. The Company gained access to this space in January 2024 and established the ROU asset and lease liability. Total future lease payments are expected to be $2.8 million over 5.0 years. The lease contains rent escalation clauses based on increases in base rent, real estate taxes and operating expenses and a 10 month rent concession. In June 2024, the Company executed an amendment to its lease agreement for our Chicago, Illinois office. The amended lease agreement provides access to temporary office space from October 2024 until September 2025, shortens the lease term for certain existing office space from September 2026 to September 2025, which will result in a one-time early termination fee, and extends the lease term of remaining existing office space from September 2026 to September 2037. As a result of the amended lease agreement the Company remeasured the existing ROU asset and lease liability based on the terms of the amended lease agreement. Total future lease payments are expected to be $16.7 million over 12.9 years, which is net of the landlord provided tenant improvement allowance of up to $8.0 million, as specified in the lease. The lease contains rent escalation clauses based on increases in base rent, real estate taxes and operating expenses and a 12 month rent concession. The components of operating lease expense recorded within general, administrative and other in the Condensed Consolidated Statements of Income (Loss) were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Operating lease cost (1) $ 2,078 $ 2,249 $ 8,026 $ 6,051 Variable lease cost (2) 840 1,034 2,917 3,418 Less: sublease income 50 49 165 130 Total lease cost $ 2,868 $ 3,234 $ 10,778 $ 9,339 ____________ (1) Includes $0.1 million of short term lease expense for each of the three months ended September 30, 2024 and 2023, respectively. Includes $0.2 million of short term lease expense for each of the nine months ended September 30, 2024 and 2023, respectively. For the three and nine months ended September 30, 2024, includes lease cost for two offices in New York due to the build out of new office space. (2) Includes common area maintenance charges and other variable costs not included in the measurement of ROU assets and lease liabilities. The following table summarizes cash flows and other supplemental information related to our operating leases: Nine Months Ended September 30, 2024 2023 Cash paid for amounts included in the measurement of operating lease liabilities (1) $ 4,009 $ 6,460 Non-cash ROU assets obtained in exchange for new and extended operating leases $ 9,057 $ 34,116 Weighted average remaining lease term in years 13.7 years 12.8 years Weighted average discount rate 6.3 % 6.1 % ___________ (1) Excludes $6.3 million of cash received during the nine months ended September 30, 2024 for lease incentives received related to the New York office lease . As of September 30, 2024, the maturities of operating lease liabilities were as follows: Remainder of 2024 $ 1,109 2025 7,623 2026 5,713 2027 6,838 2028 6,661 Thereafter 67,430 Total lease payments 95,374 Less: tenant improvement allowance (8,706) Less: imputed interest (32,078) Total operating lease liabilities $ 54,590 Commitments During the three months ended September 30, 2024, the Company extended its contract for a 6.25% interest in an aircraft until September 3, 2029, and will continue to pay a fixed management fee of $0.3 million per year. The Company had $86.4 million and $85.6 million of unfunded investment commitments as of September 30, 2024 and December 31, 2023, respectively, representing general partner capital funding commitments to several of the GCM Funds. Litigation In the normal course of business, the Company may enter into contracts that contain a number of representations and warranties, which may provide for general or specific indemnifications. The Company’s exposure under these contracts is not currently known, as any such exposure would be based on future claims, which could be made against the Company. The Company’s management is not currently aware of any such pending claims and based on its experience, the Company believes the risk of loss related to these arrangements to be remote. From time to time, the Company is a defendant in various lawsuits related to its business. The Company’s management does not believe that the outcome of any current litigation will have a material effect on the Company’s Condensed Consolidated Financial Statements. Off-Balance Sheet Risks The Company may be exposed to a risk of loss by virtue of certain subsidiaries serving as the general partner of GCM Funds organized as limited partnerships. As general partner of a GCM Fund organized as a limited partnership, the Company’s subsidiaries that serve as the general partner have exposure to risk of loss that is not limited to the amount of its investment in such GCM Fund. The Company cannot predict the amount of loss, if any, which may occur as a result of this exposure; however, historically, the Company has not incurred any significant losses and management believes the likelihood is remote that a material loss will occur.

Related Party Transactions [Abstract]
Related Parties	Related Parties In regard to the following related party disclosures, the Company’s management cannot be sure that such transactions or arrangements would be the same to the Company if the parties involved were unrelated and such differences could be material. The Company provides certain employees partnership interest awards which are paid or settled by Holdings, Holdings II and Management LLC. Refer to Note 9 for further details. The Company has a sublease agreement with Holdings. Because the terms of the sublease are identical to the terms of the original lease, there is no impact to net income in the Condensed Consolidated Statements of Income (Loss) or Condensed Consolidated Statements of Cash Flows. The Company incurs certain costs, primarily related to accounting, client reporting, investment-decision making and treasury-related expenditures, for which it receives reimbursement from the GCM Funds in connection with its performance obligations to provide investment management services. The Company also incurs certain costs, primarily related to employee benefits and travel, for which it receives reimbursement from Holdings. Due from related parties in the Condensed Consolidated Statements of Financial Condition includes net receivables from GCM Funds of $7.3 million and $13.5 million and from Holdings of less than $0.1 million as of September 30, 2024 and December 31, 2023, respectively, paid on behalf of affiliated entities that are reimbursable to the Company. Our executive officers, senior professionals, and certain current and former employees and their families invest on a discretionary basis in GCM Funds, and such investments are generally not subject to management fees and performance fees. As of September 30, 2024 and December 31, 2023, such investments and future commitments were $417.1 million and $377.5 million in aggregate, respectively. Certain employees of the Company have an economic interest in an entity that is the owner and landlord of the building in which the principal headquarters of the Company are located. The Company utilizes the services of an insurance broker to procure insurance coverage, including its general commercial package policy, workers’ compensation and professional and management liability coverage for its directors and officers. Certain members of Holdings have an economic interest in, and relatives are employed by, the Company’s insurance broker. From time to time, certain of the Company’s executive officers utilize a private business aircraft, including an aircraft wholly owned or controlled by members of Holdings. Additionally, the Company arranges for the use of the private business aircraft through a number of charter services, including entities predominantly or wholly owned or controlled by members of Holdings. The Company paid, net of reimbursements, $0.6 million and $1.4 million for the three and nine months ended September 30, 2024, and $0.5 million and $2.0 million for the three and nine months ended September 30, 2023, respectively, to utilize aircraft and charter services wholly owned or controlled by members of Holdings, which is recorded within general, administrative and other in the Condensed Consolidated Statements of Income (Loss).

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate used for interim periods is based on the tax effect of items recorded discretely in the interim period in which those items occur. The effective tax rate is dependent on many factors, including the estimated amount of income subject to income tax and allocation of tax benefit to noncontrolling interest; therefore, the effective tax rate can vary from period to period. The Company evaluates the realizability of its deferred tax asset on a quarterly basis and adjusts the valuation allowance when it is expected a portion of the deferred tax asset may not be realized. The Company’s effective tax rate was 21% and 16% for each of the three months ended September 30, 2024 and 2023, respectively, and 55% and (21)% for the nine months ended September 30, 2024 and 2023. These rates were different than the statutory rate primarily due to the portion of income allocated to the noncontrolling interest holders, including profits interest expense, as well as a valuation allowance recorded against deferred tax assets and discrete tax adjustments recorded in the periods. As of September 30, 2024, the Company had $1.0 million in unrecognized tax positions and believes there will be no material changes to the uncertain tax benefits related to its uncertain tax positions within the next 12 months.

Shares of the Company’s Class C common stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, a separate presentation of basic and diluted earnings (loss) per share of Class C common stock under the two-class method has not been presented.

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for annual financial statements. In the opinion of management, all necessary adjustments (which consists of only normal recurring items) have been made to fairly present the Condensed Consolidated Financial Statements for the interim periods presented. Results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (“SEC”).
Fair Value Measurements	Fair Value Measurements The Company categorizes its fair value measurements according to a three-level hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are defined as follows: • Level 1 – Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date; • Level 2 – Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly, including inputs in markets that are not considered to be active; and • Level 3 – Inputs that are unobservable and require significant management judgment or estimation. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. The carrying amounts of cash and cash equivalents and fees receivable approximate fair value due to the immediate or short-term maturity of these financial instruments.
Investments	Investments Investments primarily consist of investments in GCM Funds and other funds the Company does not control, but is deemed to exert significant influence, and are generally accounted for using the equity method of accounting. Under the equity method of accounting, the Company records its share of the underlying income or loss of such entities, which reflects the net asset value of such investments. Management believes the net asset value of the funds is representative of fair value. The resulting gains and losses are included as investment income in the Condensed Consolidated Statements of Income (Loss). The Company’s equity method investments in the GCM Funds investing in private equity, real estate and infrastructure (“GCM PEREI Funds”) are valued based on the most recent available information, which typically has a delay of up to three months due to the timing of financial information received from the investments held by the GCM PEREI Funds. The Company records its share of capital contributions to and distributions from the GCM PEREI Funds within investments in the Condensed Consolidated Statements of Financial Condition during the three-month lag period. To the extent that management is aware of material events that affect the GCM PEREI Funds during the intervening period, the impact of the events would be disclosed in the notes to the Condensed Consolidated Financial Statements.

Recently Issued Accounting Standards	Rece ntly Issued Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures . ASU 2023-07 scopes in entities with a single reportable segment and requires those entities to provide all disclosures required in Topic 280, requires that current annual disclosures about a reportable segment’s profit or loss and assets also be provided in interim periods and requires other various new disclosures. Enhanced reporting requirements for all entities includes disclosure of (1) significant segment expenses, (2) the title and position of the chief operating decision maker (the “CODM”) and (3) how the CODM uses disclosed measure(s) of a segment’s profit or loss in assessing segment performance and allocating resources. This guidance is effective for public entities for fiscal years beginning after December 15, 2023 and for interim periods within fiscal years beginning after December 15, 2024. Companies are required to apply the amendments retrospectively to all prior periods presented in the financial statements and early adoption is permitted. The Company is evaluating this guidance and currently expects that adoption will result in new disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . ASU 2023-09 requires enhanced income tax disclosures including disclosures of specific categories in the rate reconciliation and additional information for reconciling items that meet a quantitative threshold, additional disclosures about income taxes paid, and disclosure of pre-tax income or loss from continuing operations disaggregated between domestic and foreign income or loss. This guidance is effective for public business entities for fiscal years beginning after December 15, 2024. Companies should provide the enhanced disclosures on a prospective basis, however retrospective application is permitted. Early adoption is permitted for annual financial statements that have not yet been issued. The Company is evaluating this guidance and currently expects that adoption will result in enhanced income tax disclosures.
